    Opis:
    For five patients representing different clinical cases the effectiveness of hearing aids adjusted to the individual hearing impairment and with the electroacoustic parameters established on the basis of different algorithms has been evaluated. The results permitted formulation of the rules optimising the effectiveness of the hearing aid use, especially in speech intelligibility.

    Opis:
    The purpose of the study was to determine the optimal hearing aid fitting procedure for a patient with well diagnosed high-frequency dead regions in both cochleas. The patient reported non-symmetrical hearing problems of sensorineural origin. The presence and frequency limits of dead regions was measured using the Threshold Equalizing Noise test (TEN). For binaural amplification four pairs of hearing aids were used. Three pairs of hearing instruments used were independent pairs with similar hearing aids in each pair. One pair of hearing aids was a pair of dependent devices with an ear-to-ear function. Two fitting methods were used: DSLi/o and NAL-NL1 and four different strategies of fitting were tested: the initial fitting based on the DSLi/o or NAL-NL1 method with necessary loudness corrections, the second fitting taking into account all available functions of hearing instruments, the third fitting (based on the second one) but with significantly reduced amplification well above one octave of frequency inside dead region and the final fitting with significantly reduced gain slightly below one octave inside dead regions. The results of hearing aids fitting were assessed using the Abbreviated Profile of Hearing Aid Benefit procedure (APHAB).

    Opis:
    In structural studies on biological materials, among other methods, electrical techniques are used widely. Temperature dependence of electrical conductivity is a method permitting studies on denaturation, glass transition and water release - processes, which occur in solid-state proteins. Variations of amplitude and temperature of the peak on the recorded thermogram make it possible to draw conclusions about thermal stability and physicochemical processes occurring in the studied biological material. The shape of experimental curve is material-related and depends upon its "history". The paper is based on experimental results obtained mainly for collagen.

    Opis:
    Myofascial pain syndrome is sensory, motor, autonomic disorder caused by the occurrence of trigger points (TrP). In literature the possibilities of deactivating TrPs through exposure to magnetic field (MF) can be noticed. The aim of current research is an attempt at answering the question whether MF changes TrP activity. Tests were carried out on 22 volunteers, who were divided into three groups. First was exposed to static MF using MagneticUnit discs, second was exposed to slow changing MF using Viofor-JPS. The third was exposed to magnetoledotherapy, also using Viofor-JPS.

    Opis:
    The purpose of this study was to assess if 65 dB and 4000 Hz stimuli affect postural stability of young normal hearing people. Methods: Posturography examinations belong to clinical tests which evaluate the motor skills. Posturography can be divided into static posturography and dynamic posturography. In both, static posturography and dynamic posturography, patient stays on the platform with opened and closed eyes, but in the case of dynamic one, platform is unstable. In this study the Multitest Equilibre platform produced by FRAMIRAL was used. Patients took part in tests with opened and closed eyes, on stable and unstable platform. Additionally patients were exposed to 65 dB and 4000 Hz acoustic stimuli. The sound pressure level, and frequency was belonging to the best audibly frequency range. Results: Parameters such as velocity and surface were examined. The difference between velocity measured with acoustic stimuli and without acoustic stimuli was observed. On the other hand there was no difference in surface results. Conclusions: The statistically significant difference between velocity of patients center of gravity movements, measured on unstable platform, in the presence of 4000 Hz, 65 dB acoustic stimulus and without additional disturbances was observed.

    Opis:
    The LED light therapy and magnetostimulation is an innovative method of treatment used in Viofor JPS System. Simultaneous application of both types of electromagnetic radiation increases the therapy effectiveness by the synergy effect. It is recommended in analgesic, anti-inflammatory treatment, and to support immune system of the organism. The mechanism of biological effect of variable magnetic fields and light are of similar nature at the tissue level. When applying magnetostimulation and light together, it shortens the time of therapy. The LED light therapy and magnetostimulation is supposed to be an alternative supporting method to therapies used to treat tinnitus so far.

    Opis:
    Commercial seed lots of onion (Allium cepa L.) of the cultivars "Octavia" and "Eureka" were soaked for 12 h in water of the temperature 20°C, then they were exposed to low frequency magnetic field (20 mT) for 10, 30, and 60 min. The field was generated using a standard device for magnetic stimulation VIOFOR JPS applied in human medical treatment. Next, the seeds were evaluated for energy and capacity of germination, length of the received germs as well as fresh masses of the obtained seedlings using the routine methods recommended by the International Seed Testing Association. For the seeds of the cultivar "Octavia", the field did not affect the energy of germination, however it did improve in all tested treatments their germination capacity. In the best of them (60 min), the germination capacity increased by 4.6%. For the seeds of the cultivar "Eureka", the tested field increased their energy of germination, which improves evenness of plants emergences in the field and has a significant importance for horticultural practice. When the seeds were exposed to the field for 60 min, their germination energy increased from 40% (control) to 63%. This result was accompanied by no differences in both length of germs and fresh masses of the received from them seedlings.

    Opis:
    One of the methods for objective evaluation of the hearing system is based on acoustic otoemissions. Particularly promising is the method based on measurement of the distortion product of otoacoustic emission as it is connected to the problem of tinnitus. Slow-varying magnetic field of low induction has been used in therapy of many diseases and ailments. It is expected that magnetostimulation will be effective in treatment of certain types of tinnitus by inducing the return of the organism to homeostasis. The aim of this study was to identify the changes in distortion product of otoacoustic emission levels in patients, prior and after the magnetostimulation. However any significant changes were found among patients with tinnitus, for the control group statistically important changes in distortion product of otoacoustic emission levels were observed.

    Opis:
    Elaboration of a new method of teaching spatial orientation to blind and visually handicapped persons base on urban environment sounds was shown. Task 1 is a questionnaire inquiry on the problems of the blind moving in a big city. In Task 2 a preliminary selection and classification of the acoustic signals and vibrations that can be useful for spatial orientation was made. In Task 3 an analysis of acoustic signals for sound signalisation at pedestrian crossings was made. Some solutions for acoustic signalization were proposed. In Task 4 sounds and vibrations necessary for a library of acoustic events and situations characteristic of a city were recorded. In Task 5 the library was created and arranged to be ready to be used by teachers in the spatial orientation training. The most important outcome of the study was to develop a method of spatial orientation teaching with employment of sounds and verification of the method (Task 6). After verification it is concluded that the method is useful for spatial education of the blind at different levels of their education.
